Þykkt álpappírs fyrir matvælaumbúðir er yfirleitt á milli 0.015-0.03 mm. Nákvæm þykkt álpappírs sem þú velur fer eftir tegund matvæla sem verið er að pakka í og æskilegt geymsluþol.
Fyrir mat sem þarf að geyma í langan tíma, mælt er með því að velja þykkari álpappír, eins og 0.02-0.03 mm, til að veita betri vörn gegn súrefni, vatn, raka og útfjólubláa geisla, thereby protecting the nutrients of the food from being destroyed and extending the shelf life of the food. Shelf. For short-term preservation of food, such as candy, súkkulaði, o.s.frv., you can choose thinner aluminum foil, such as 6μm,13(6míkron álpappír, 13mic álpappír) álpappír. It is thin and transparent, which can better fit the food and reduce the penetration of oxygen and moisture. Thereby extending the shelf life of food.
Lightweight Packaging: For packaging lightweight foods or covering cutlery, thinner aluminum foil (approximately 6 til 9 míkron) is sufficient. This thickness provides flexibility and ease of use.
Medium packaging: For packaging medium-weight items such as sandwiches, baked goods, or individually wrapped foods, aluminum foil with a thickness of approximately 9 til 12 microns may be appropriate. This thickness provides a good balance between strength and flexibility.
Heavy-Duty Packaging: Þykkari álpappír (approximately 12 til 15 míkron) is recommended for heavier or sturdier foods, such as roasts, meats, or foods that require long periods of storage or cooking. This provides extra strength and durability to withstand handling and cooking processes.
Auk þess, the material and quality of aluminum foil are also factors that need to be considered when selecting. High-quality aluminum foil should have good corrosion resistance, high temperature resistance and mechanical strength to ensure food safety and hygiene.
